SNAP-FASTENER-UPSETTING MACHINE.

Specification of Letters Patent.

Patented Jan. 10, 1922.

Application filed October 30, 1920. Serial No. 420,794.

To all whom it may concern:

Be it known that I, THOMAS F. MORRIS, a citizen of the United States, residing at Waterford. in the county of Saratoga and State of New York, have invented certain new and useful Improvements in Snap- FastenerUpsetting Machines, of which the following is a specification.

This invention relates to an improvement in snap fastener upsetting machines, in the use of which the respective parts ofthe male and female portions of the fastener are secured together and to the fabric.

The invention is particularly designed for applying glove fasteners of the snap type, and is constructed with a view to providing an automatic machine wherein the operator is positively safeguarded against injury in the operation of the machine.

is is well understood each male and female portion of the snap fastener is made up of two portions or parts, a formed part to be passed through an opening in the glove or other article and rest against one side or surface of the fabric and a washer or equivalent part to rest against the opposite side of the fabric; The operator assembles these parts in position, arranges the assembled parts on the anvil of the machine, and hen upsets or otherwise clamps the two parts together in the operation of the machine. In rapid operation it not infrequently happens that the operator will fail to remove the finger applying the final part to the anvil position in time to escape the upsetting die, and injury results.

The present invention entirely obviates the possibility of such injun by rendering the machine entirely automatic in its action,

and holding it against operation until tripped by the operator in reaching for a part of the next fastener part to be subsequently applied. In other words, the operator must assemble a fastener complete for the upsetting operation on the anvil, and then in reaching for the next part of the fastener to be applied in the next glove opening. trips the machine and sets it in operation to upset the fastener parts already on the anvil. The machine automatically stops following each upsetting operation, and cannot be again tripped until the hand of the operator is reaching for another part of a subsequent fastener, which of course positions the operators hand entirely away from the machine,

The present machine embodies another safeguard for the same end, in thatthe upsetting die is carried on a member normally to one side of the anvil position, the die carrier being moved into position under the plunger in the operation of a lever connected through a spring with the carrier, so that if the hand or fingers of the operator are in the way of the carrier, the latter will on contact with the hand or fingers be brought to rest short of the anvil position, so that no actual upsetting operation can take place. Thus the operator is completely safeguarded against injury.

It is admittedly true that in previoushand operated machines of this type, the operator,

invention, the operation is automatic, and.

in addition to the safeguarding features referred to, an exactly identical and similar pressure is applied to the fasteners of a particular type, so that all fasteners are equally and efficiently secured.

The invention is illustrated in the accompanying drawings, in which:-

Fig. 1 is a view in elevation partly in section of the improved machine.

Fig. 2 is a side elevation of the same.

Fig. 3 is a section of the machine taken just above the die carrier, showing more particularly the movement of the die carrier to and from operative position.

Fig. 4 is a view in elevation showing the hopper arrangement in relation to the operating plate.

The improved machine comprises a framework including a pedestal 1 supported above the operating table, as shown. The pedestal has upstanding spaced members 2 to form a bearing for a shaft 3, on which centrally between the arms is a cam 4, adapted in each revolution of the shaft 3 to reciprocate a plunger 5 guided in the pedestal.

A die carrier is pivotally supported on the framework to swing to and from a position below the plunger, such carrier comprising a block 6, pivotally mounted at its rear end, and carrying a'rotatable table 7 at its forward end. The table comprises upper and lower plate sections 8, in which in concentric relation with the pivot of the tableis mounted the respective die rods. These rods, which are independently formed at their lower ends for the respective male and female portions of the fastener, are adapted to be moved, through turning of the table into operative position in the carrier, a pin 9 securing the table in fixed position to use the particular die rod desired. The die rods are each spring pressed in the up warddirection. through springs 10 coiled about the rods and bearing against the lower plate of the table, and an offset or washer on the rod.

The die carrier is operated through a cam 11 on the shaft 3, which is formed as shown to engage the upper end of a lever 12 in each revolution of the shaft, and move such lever on its frame pivot 13 to cause the lower end 14 thereof, through a spring 15, to move the die carrier so that the selected die rod will be positioned beneath the plunger 5.

Aspring 16 connected to the upper end of the lever and the frame insures that the lever be held in cooperation with and follow the cam, thus a properoperation of the lever in both directions is secured.

An anvil 17 is arranged on a lower portion of the main frame below the plunger 5, in position to receive the upsetting action of the die rod actuated by such plunger, this anvil. being formed to 'removably receive anvil-blocks 18 of different forms, as is re quired in upsetting the male and female parts of the snap fastener.

The anvil blocks 18 rest upon a stiff spring 19, capable of adjustment through a set screw 20 to secure he desired rigidity of movement of the anvil-block and also to position it vertically for the stroke of the die rod." v i The shaft 3 is driven from a continuously operated sprocket wheel 21 secured to one member 22 of a clutch, the other member 23 of which is fixed to the shaft. The movable clutch member is spring pressed toward the fixed clutch member through a spring 2-1, and a lever 25 is provided with a yoke to engage an annular groove in the movable clutch member for normally holding the movable clutch member free of engagement with the fixed, clutch member. The lever is pivotally supported on the main frame and has a lateral extension 26 adapted to overlie the end of a trip bar 27, which latter is notched or cutaway for a portion of the supper end, as at 28. i The trip bar, which is pivotally connected to the main frame is connected at the lower end to a rod 29, which 111 turn 1s connected to a projection 30 extending upwardly from a plate 31, pivotally mounted at 32 on the edge of the operating table adjacent the anvil.

The clutch is designed to be automatically disengaged at each revolution, it being provided for this purpose with a block 33 slidably mounted in a recess in the block supporting lever 25. Thisbloclr 33 has one end arranged to contact with the lever 25, and the opposite end adapted to be engaged by a wedge 34 secured on and movable with the fixed clutch member 23. In each revolution of the shaft therefor, and at an appropriate period in such revolution, the clutch wedge member 34 moves the bloclr 33Jlaterally to force the lever 25 to a position to disengage V eluding a brake drum 36 forming an integral part of a cam 37 secured upon the shaft. This cam has a projection38 ada )ted to engage a spring 39 secured on the frame and overlying the cam. To the free terminal of this spring is connected a leather strip 40, which strip overlies the brake drum 36, with its opposite end fixed to the frame. As the cam projection '33 depresses thespring 39, it will tighten the brake band -10 about the drum 36, checking the movement of the shaft 3 and causing it to stop at the same point in each revolution.

Aspreviously explained, the parts of both the male and female sections of the fastener, that is the two metal elements making up the section, are separately applied, one to one side of the fabric, as a gloveand projecting through a hole therein, as indicated at 41, the other part being applied. over such first part. and to the'opposite side of the fabric. This operation is performed by the operator, who then places the assembled fastener'parts and fabric or glove over the anvil, as indicated, holding the article in this position with two fingers pressing the article against the anvil, well below the 1u per end thereof. As an essential feature of the safeguarding principle of the invention, the respective parts of the fastener sections are arranged in se )arate hopper containers, as shown, from which they are quickly and convenientlyremoved by the operator as desired. These hoppers are arranged in pairs on a rotating base mounted on the operative table one pair for the parts of one fastener section and the other pair for the dicated in Fig. 1.

parts of the other section. As it is customary for the operator to apply all the fastener sections of like character to the gloves in hand, and then apply all the fastener sections of the other kind, itis necessary to describe the use of these containers for but one fastener section. These containers of one pair. as 42 and contain the respective parts of such particular fastener section, the hopper 42 containing the main part and the hopper e3 containing the washer or clamping part, Now it is to be noted that the hoppers are so mounted that the free edge of the discharge lip of hopper 4:2 is immediately adjacent and above the upper edge of the plate 31, which is connected to the trip bar as previously described.

The edge of this plateadjacent the discharge lip of the. hopper as is cutaway at it to avoid engaging the plate in removing a fastener part from such hopper.

Vie will assume the machine set, a glove fastener section assembled in the glove opening, and the parts on the anvil, as-in- Now as the operator reaches with the righthand, the left hand means while holding the glove and parts on the anvil, to get the main part from the hopper 12 for the next hole in the glove, the plate 31 is rocked, the trip rod moved suiliciently to let the lever 25 move to, cause clutch cooperation, the shaft 3 is rotated, the carrier moved to position the selected die rod beneath the plunger 5, and the lat tcr operated by the cam t to force said die rod down and complete the setting of the fastener section on the anvil. All this occurs practically as the operator is withdrawing the initial part for the next fas tenor section, thus taking her hand entirely out of the way of the die rod and avoiding possible injury. Havin placed the initial part taken from the hopper 12 in the glove hole, the operator reaches into the hopper lip for the other or second part of such fastener section, but as the plate 31 is cutaway at 14 adjacent this hopper, no machine operation occurs.

Of course the base on which the pairs of containers are mounted is simply reversed when fastener parts from the other containers are desired, the operation with such parts being identical with that just described.

The die carrier is moved by a lever con nected with such carrier by a spring as 15, so that if automatic operation of the machine should take place while the operators hand is above the anvil, the movement of the die carrier will be arrested by the hand, and no movement of the die rod will follow the movement of the plunger. Thus injury under such, ordinarily very infrequent conditions is avoided.

The die carrier may be temporarily secured in operative position by spring arms secured to the adjacent frame bar and underlying the carrier block, with offsets e6 over which the block rides when in opera- \Vhat is claimed, is
